Description
4-Neck flask 4000 ml with straight side necks is a large-capacity multi-neck round-bottom flask designed for preparative distillation, synthesis and multi-port reaction work. The vessel provides a centre neck together with straight side necks, each equipped with NS 29/32 ground joints for standardised connection of condensers, mechanical stirrers, addition funnels and temperature probes. Its 4000 ml nominal volume accommodates larger batch sizes while the four-neck arrangement permits simultaneous reagent addition, reflux and process monitoring. Supplied by manufacturer Witeg, the flask is well suited to organic synthesis, fractional distillation trains and continuous laboratory processes that benefit from stable multi-component glassware assemblies. Straight side-neck geometry minimises spatial interference when several accessories are mounted in parallel, supporting compact and secure set-ups on heating mantles or stands. The design serves as both reaction and receiving flask in distillation and work-up sequences. Laboratories engaged in scale-up chemistry, multi-step organic preparations and controlled-atmosphere reactions will find the NS 29/32 joint system compatible with common laboratory glassware inventories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about 4-neck flask 4000ml straight side necks ST29/32
What is this article?
4-neck flask 4000ml straight side necks ST29/32 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Matériel de laboratoire.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
